'NXOpen.UF.UFCurve.Line' cannot be converted to 'NXOpen.DisplayableObject'. D:

[EngProgrammer]

Within NXOpen I am trying to blank and/or more a line created with

Dim line1 As NXOpen.UF.UFCurve.Line = New NXOpen.UF.UFCurve.Line

 

[EngProgrammer]

Sorry. Didn't finish the thread.

I am using

workPart.Layers.MoveDisplayableObjects(257, {line1})

But, NX is saying to a displayable object. What is the work around for this? Rather than instancing an NX line instead of a UFUNC line.

thanks

Have you tried casting it to a displayable object?

Nevermind, that won't work. NXOpen.UF.UFCurve.Line is a structure, not a class. Why the need to use UF.UFCurve.Line instead of a NXOpen.Line object?

Just some legacy code. Which is faster?

An NXOpen.UF.UFCurve.Line is not a Displayable object. It doesn't live in an NX part file, and it doesn't have a layer. So, obviously you can't move it to a new layer. You can't display it, either.

If you want a "regular" NX line (an object in an NX part file), you should be using an NXOpen.Line object or a Snap.NX.Line object. With these, you can display them, change layer, change color, and so on.

NXOpen.UF.UFCurve.Line object is displayable. It is displayed in the ug graphics window but doesn't appear in the part navigator. Also, it can be manually blanked. I don't understand why you are saying it can't be displayed. Please explain.

If you consult the .net ref API documentation, you will find that NXOpen.UF.UFCurve.Line is a wrapper for the UF_CURVE_line_s structure (aka UF_CURVE_line_t and UF_CURVE_line_p_t); it is NOT a line object or an equivalent reference to a line object. It is simply a structure that is used to hold some information about a line object (specifically the start and end points, saved as arrays of doubles). As a data structure, it is not a displayable object. If you need to edit the line object, you will need to get a valid reference to the line object.
